Nosler 11912 Premium Brass Cases 338 RUM Unprimed 25 Count

The Nosler 11912 Premium Brass Cases deliver exceptional consistency for 338 Remington Ultra Magnum handloaders demanding match-grade performance. These unprimed cases feature precise manufacturing tolerances that ensure uniform powder capacity and reliable ignition across multiple reloading cycles.

What Makes This Different

Nosler's proprietary brass alloy composition provides 15-20% longer case life compared to standard military brass. Each case undergoes weight sorting within ±0.5 grains and dimensional inspection to maintain consistent internal volume. The annealed neck and shoulder areas resist work hardening while maintaining proper tension for bullet seating.

Key Features

• Premium brass alloy construction for extended reloading life
• Weight sorted within ±0.5 grains for consistent performance
• Chamfered case mouth and deburred flash holes from factory
• Uniform wall thickness maintains consistent powder capacity
• Proper annealing prevents premature case failure
• Ready-to-load condition requires no additional preparation
• 25-count packaging ideal for precision load development

These cases excel in long-range hunting applications where the 338 RUM's magnum performance demands reliable brass. The uniform case capacity translates to consistent velocities and improved accuracy at extended ranges. Hunters pursuing elk and dangerous game rely on this consistency for shot placement confidence. Competition shooters appreciate the reduced velocity variation that improves group sizes.
